Thanks, Pandaneko. Is the mission being well-covered by the Japanese media? Wondering if you and other people in Japan will get updates faster than the rest of us.


Not at all. I am upset about it, actually. There were many reporters at the press conference from many different media groups, but they
do not seem to write about rovers. My guess is that their bosses ignore them and send their draft articles straight into dustbin.
MASCOT may get more publicity when it lands on Ryugu because it is not Japanese by origin.

Translation of the latest input from JAXA. Please refer to the main page of JAXA in Japanese as there is no Engolish version yet available
with corresponding photos.

2 rovers were seperated from H2 on 21 Sept. (13:06 JST)

It has been confirmed that both safely landed on Ryugu and are both healthy. They took photos and obtained other data and
that they are even hopping on Ryugu surface has been confirmed.

What follows are the photos from these rovers.

Figure 1:

13:08 on 21 September 2018 by rover 1A, in colour, immediately after seperation while it is spinning. In the photo an object
above is H2 and object bellow is Ryugu surface. Blurring is due to the spin.


Figure 2:

13:07 JST on 21 September 2018 by rover 1B, in colour, immediately after seperation. Righhand below is Ryugu.


Figure 3:

11:44 on 22 September 2018 by rover 1A, in colour.

This photo was taken while it was hopping. Righthand half is Ryugu.


MINERVA-Ⅱ operati0n will continue and there will be more photos.

Now that's worth the wait.... that's one of the coolest shots I've ever seen; low quality but astonishing (reminds me of the Huygens surface pics!)

Hopefull there will be some pictures taken when the rover is not in mid-bounce! And some scale information would be helpful, like, is that rock the size of a house or the size of a footstool?

This is a picture from MINERVA-II1. The color photo was captured by Rover-1A on September 21 around 13:08 JST, immediately after separation from the spacecraft. Hayabusa2 is top and Ryugu's surface is below. The image is blurred because the rover is spinning. #asteroidlanding

HAYABUSA2@JAXA‏ @haya2e_jaxa
Photo taken by Rover-1B on Sept 21 at ~13:07 JST. It was captured just after separation from the spacecraft. Ryugu's surface is in the lower right. The misty top left region is due to the reflection of sunlight. 1B seems to rotate slowly after separation, minimising image blur.

This dynamic photo was captured by Rover-1A on September 22 at around 11:44 JST. It was taken on Ryugu's surface during a hop. The left-half is the surface of Ryugu, while the white region on the right is due to sunlight. (Hayabusa2 Project)

Outstanding!

I have one thing about which I am curious. The final of the three images states it was taken while its rover was in mid-hop. I'm wondering why any hopping activity was occurring without any commands sent from Earth -- I didn't see any indication of pre-programmed hopping set up in the deployment and landing timelines that JAXA posted. And from the other statements made, both pre- and post-landing, I can't see any indication that hopping actions were commanded during this time.

I *did* see something that indicated that the rovers were expected to "bounce" and take a good 15 minutes to settle down onto the surface in a stable, non-moving attitude.

Could the caption which indicates the rover was hopping really indicate that it was in a bounce and not in a deliberate or commanded hop?

The difference would be like stating that, say, Opportunity was "roving" as it bounced to a stop within Eagle Crater...

The blurriness rather reminds me of the first image from Philae, though it was quite clear by that point the landing systems had not worked!
Perhaps one or both just hit a boulder at a certain angle and bounced a bit more?
I wonder if the mothership took any pictures after deployment, like Rosetta?

Great pictures! I was reminded of the images from Sojourner, especially the little colour camera. Ted Stryk did some great processing of those.

Let's hope for lots more.

Congratulations to JAXA!

Much thanks to you, Pandaneko, for keeping us posted.

You would absolutely pre-program a long sequence of activities for them, including hops, imaging, temperature measurements and comm passes. Our situational awareness for them is poor. We don't know what way up they will land, if they'll get stuck under a boulder etc etc

Having an autonomous sequence of imaging and hopping would be the only rational way to execute a mission like this.

Well Done JAXA!
My poor little deconvolving suite struggle for about an hour to converge on a better image of H2 a few hundred feet away
No luck but here is a gif of its best try

Amazing pictures from a tiny world! Congratulations JAXA!

Here is an animation showing the approach of Hayabusa 2 from 20km to 80m:
